Trapp sets off with his mom and their dog, Cairo, on a two-day Amtrak journey to compete in the National Science Challenge in Washington, D.C.

Trying to be a Good Samaritan on the train, he unwittingly becomes embroiled in an ingenious plot that may have links to terrorists. Federal agents (first seen in Pearson's adult thriller Cut and Run) track Steel and his newfound science geek accomplice, Kaileigh Augustine, as they attempt to put together the pieces of a complex puzzle. Using Steel's science contest invention - and with the help of Cairo - Steel and Kaileigh lead listeners on an action-packed adventure as they attempt to prevent the unimaginable, before it's too late.
